Benzene can be prepared from ethyne through a process called electrophilic aromatic substitution. In this process, ethyne reacts with a strong acid catalyst such as concentrated sulfuric acid to form benzene. The high temperature required for this reaction causes the triple bond in ethyne to break and the resulting carbons bond to form a benzene ring.

What Aromatic Hydrocarbon has been prepared in the reaction between Sulfuric Acid and Benzene?
Benzene sulfonic acid is produced in the reaction between sulfuric acid and benzene. This reaction involves the substitution of a hydrogen atom on the benzene ring with a sulfonic acid group (SO3H).
How do you prepare cyclohexane from benzene?
Cyclohexane can be prepared from benzene through catalytic hydrogenation. In the presence of a catalyst such as platinum or palladium, benzene can be reacted with hydrogen gas under high pressure and at high temperature to produce cyclohexane.
Does ethyne react with bromine?
Yes, ethyne (acetylene) can react with bromine to form 1,2-dibromoethane. This is an addition reaction where the bromine atoms add across the carbon-carbon triple bond in ethyne.
Another name for acetylene?
Acetylene (C2H2) is also known as ethyne. It is the simplest alkyne.
What is the balanced equation for the complete combustion of Ethyne?
The balanced equation for the complete combustion of ethyne (C2H2) is: 2C2H2 + 5O2 -> 4CO2 + 2H2O
What is the starting material to produce benzene?
it can be prepared from using acetylene
How prepare benzen hexa clorief from benzen?
The Benzene hexa clorief is prepared by light-induced addition of chlorine to benzene.
A mixture is prepared using equal masses of the two volatile liquids benzene and ethanol What is the mole fraction of benzene in this mixture?
0.371

What is the colour ethyne after combustion?
By combustion ethyne is transformed in carbon dioxide and water.
What more dense oxygen or ethyne?
Ethyne is denser than oxygen. The density of ethyne (acetylene) is about 1.097 g/L at STP, whereas the density of oxygen is around 1.429 g/L at STP.
Is ethyne polar?
polar
What is the number of hydrogen atoms in a molecule ethyne?
The chemical formula of ethyne (acerylene) is C2H2 - two hydrogen atoms.
What molecules are nonpolar bromine pentafluoride tetrachloroethene chlorine trifluoride phosphine ethyne?
ethyne (or acetylene) is non polar
Does ethyne react with bromine?
Yes, ethyne (acetylene) can react with bromine to form 1,2-dibromoethane. This is an addition reaction where the bromine atoms add across the carbon-carbon triple bond in ethyne.
How do carbon atoms form a benzene ring?
Carbon atoms in a benzene ring are bonded in a hexagonal ring structure with alternating single and double bonds. Each carbon atom forms three sigma bonds with neighboring carbons and one pi bond from the extra electron in the p-orbital. This delocalized pi electron system creates the aromatic stability characteristic of benzene.
